Setting up an external Zookeeper Solr Cluster

This is a step by step instruction on how to create a cluster that has three Solr nodes running in cloud mode. These instructions should work on both a local cluster (for testing) and a remote cluster where each server runs in its own physical machine. This was tested on Solr version 5.4.1 and Zookeeper version 3.4.6

Installing Solr and Zookeeper

Download and extract Solr:
- curl -O http://archive.apache.org/dist/lucene/solr/5.5.3/solr-5.5.3.tgz
- mkdir /opt/solr

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

Redux Chaos Monkey

This is a proof of concept which allows you to replay system events in a random order each time to make sure your UI can tolerate variable states.

I'm not sure if this is worthy of its on open source project with additional features like changing play back time, whitelisting/blacklisting actions etc but figured I'd put this out there to see if it piques anyones interest.

See a video of this in action here: [https://www.youtube.com/watch?v=wkoukONfwmA](Video on YouTube).

For those of you asking about my "redux mental breakthrough":

I've struggled with how to keep the state of multiple instances of the same component class in redux. I kept thinking that I had an "unkown number" of instances and would need to somehow carve out a piece of state when the new instance was mounted.

I don't know why I was thinking this way. Thinking is hard, isn't it? (I'm in the UK and they often say "isn't it?" after asserting something and I love it, anyway....)

	To install virtualenv via pip
	$ pip3 install virtualenv

	Note that virtualenv installs to the python3 directory. For me it's:
	$ /usr/local/share/python3/virtualenv

	Create a virtualenvs directory to store all virtual environments
	$ mkdir somewhere/virtualenvs

	Make a new virtual environment with no packages

	import { combineReducers } from 'redux';
	import users from './reducers/users';
	import posts from './reducers/posts';

	export default function createReducer(asyncReducers) {
	return combineReducers({
	users,
	posts,
	...asyncReducers
